MEAT-MIXER.

SPECIFICATION formingpart of Letters Patent N 0. 637,765, dated November 28, 1899.

Application filed March 24, 1899. Serial No. 710,279. No model.)

which the following is a specification.

My invention relates to machines for mixin g or kneading meat, and particularly to the class described in my application Serial No. 701,074, in which a series of reciprocating pestles are used to imitate the operation of the fist of an operator in mixing the meat and rubbing in or diffusing the seasoning through same.

The main objects of my present invention are to avoid the necessity of reversing the relative movement of the meat-receptacle and the mixing device, to provide a machine which will occupy less space than the one described in my application hereinbefore mentioned, and to simplify the operating mechanism. To this end I provide a machine in which the relative movement of the receptacle and the mixing device is rotary instead of longitudinal and reciprocating.

In the accompanying drawings, Figure 1 is a front elevation of a mixer constructed according to my invention with the frame and wall of the receptacle partly broken away. Fig. 2 is a side elevation of the same, partly broken away. Fig. 3 is a side elevation of one of the pestles with the shaft and guide in section.

The device shown consists, mainly, of the revoluble platform or meat-receptacle l and a series of reciprocating pestles 2, operating at one side of the axis of the receptacle. The receptacle 1 has the central pivot 3, supported in the member 4 of the frame. The annular rack 5, rigidly secured to the receptacle, meshes with the pinion 6 on the shaft 7. The shaft 7 is supported in the bearing 8 on the frame. The pulley 9 is rigidly mounted on said shaft and connected with the pulley 10 through the belt 11. The pulley 10 is rigid on the shaft 12, which is journaled in the upper part of the frame. The pestles 2 are eccentrically mounted on the shaft 12, the same having collars 13, with rotary eccentric members 14 therein, which are rigid on the shaft.

The pulley 15 is also rigid on the shaft 12 and connects through the belt 16 with suitable power apparatus. (Not shown.) The pestles 2 each have a head 17 thereon, provided with the ribs or ridges 18. The member 19 of the frame has a number of orifices 20 therein for receiving and guiding the pestles. The ori fices 20 are slightly larger than the pestlearms, permitting the free sliding movement of the latter and also permitting same to have the swinging movement imparted by the eccentrics 14, coacting with the guide 19. The eccentrics 14 are preferably mounted on the shaft so that some of the pestles will be at the upper limit of the stroke While others are at the lower limit, the same being arranged alternately.

The operation of the device is as follows: The power being applied at the belt 16, driving same in the direction of the arrow, will rotate the eccentric 14 in the same direction,

causing the pestles at their free ends to pitch.

backward and down and then forward and up, as indicated by the dotted arrow-line in Fig. 3. The pulley 9 is driven in the same direction through the belt 11. The pinion 6, meshing with the rack 5, revolves the receptacle 1 in the direction of the forward pitch of the pestles, as indicated by the arrow.

It will be understood that the device shown may be altered in numerous Ways Without de parting from the spirit of my invention. I therefore do not confine myself to the details of construction shown.

What I claim, and desire to secure by Letters Patent, isp 1. In a meat-mixer, the combination of a supporting-frame; a platform or receptacle for supporting the meat; a mixing device comprising a series of pestles having a longitudinal reciprocating movement, and a lateral nal reciprocating movement, and a lateral ism for imparting such movement to said pesnip'vement iii proximity to said platform, and signed by me' at Chicagd, I 11inois, ti1is each having a beaded or 'idged head adapted day of March, 1899.
